Description

Sliding opening and closing mold device and a method of manufacturing a circular tube using the same

The present invention relates to a mold apparatus for molding a concrete circular tube, and more specifically, to a concrete circular tube that is filled in to form a concrete tube and is contaminated or fixed while spilling out and staining a molding mold or a fixing means for fixing the molding mold. It is improved so that the mold device can be easily operated with little time and manpower.

As is well known, the concrete circular pipe is used in a place where earth pressure acts on the pipe body (or body) or only external pressure such as vehicle load acts, and is used as a water and sewer pipe by embedding it in a building, road, or ground.

In general, a concrete circular tube faces each other and forms an outer wall separated into two, an inner wall forming an inner side, and a concrete circular tube using concrete in a forming mold consisting of a table supporting the lower end of the outer wall and the inner wall.

In the conventional molding mold, the inner wall is assembled on the table top so that the inner wall is erected, and the two outer walls separated by the inner wall are brought into close contact with each other by fastening screws such as bolts to fix it, and then the empty space between the outer wall and the inner wall (or filling space) After curing the concrete, separate the outer and inner walls in the reverse order to demold the molded concrete round tube.

However, if the bolts are not firmly fastened in the step of adhering two outer walls facing each other and fastening screws such as bolts, a gap is created between the outer wall and the outer wall that are in close contact, and the filled concrete flows out and forms a concrete circle. There is a problem in that the tube is not molded correctly, resulting in defective products.

In particular, the concrete flowing through the gaps in the outer wall stains and contaminates the fixing means such as bolts that fix between the outer walls and the outer wall in close contact, and the other parts around the molding mold, etc. As this time passes, it becomes stuck and cannot be separated or demolded, making it difficult to use.

In addition, as described above, it requires a lot of time and manpower to operate a molding mold or a mold device, such as completely fastening screws such as bolts with a fixing means so that concrete does not flow out through the gaps between the outer walls. There is a problem with falling.
